: Utilized when direct access is restricted. It employs tools like mirrors, telescopes, borescopes, or fiber-optic cameras. Translucent Visual Examination
Detecting surface cracks, porosity, lack of fusion, and improper geometry. Component Integrity: asme section v article 9
Article 9 provides the methodology for visual inspections when required by referencing Code Sections (e.g., Section VIII for pressure vessels or Section I for boilers). It is designed to detect surface conditions, including: (undercut, porosity, and spatter). Physical damage (corrosion, erosion, or mechanical wear). Structural alignment and general workmanship. Leakage during hydrostatic or pneumatic testing. Mandatory Procedural Requirements : Utilized when direct access is restricted
: All visual examinations must follow a detailed written procedure. Component Integrity: Article 9 provides the methodology for

specifically outlines the mandatory requirements for Visual Examination of welds, base materials, and clad surfaces. It applies to:
| Nonconformance | Why It’s a Problem | |----------------|--------------------| | No light meter reading recorded | Cannot prove 100 fc minimum | | Viewing distance >24 inches without optical aid | Misses small discontinuities | | Annual eye exam missing for examiner | Invalidates examiner qualification | | Using acceptance criteria from wrong code edition | Reject/accept decisions invalid | | Remote visual without resolution chart | No guarantee of detectable flaw size |
